A book cover for retaining objects is presented including a front panel and back panel hingedly connected to form a book cover. A window extends outward from the front panel in the book cover, forming an enclosure for retaining objects between the cover and a surface proximate to the cover. The window can be clear, displaying the objects held in place thereby, and the book cover may include a closure mechanism to prevent the window from opening and letting the pieces out. The book cover may also be incorporated into an educational activity book comprising a front panel and a back panel connected to form a book cover. Puzzle pieces may be provided in one embodiment for inclusion in the cover of the book in order to assist in teaching children object association and enhancing their coordination.

A multiple piece toy in which each piece includes a base having an interconnectable peripheral edge which selectively mates with the peripheral edges of other pieces to enable multiple relationships therebetween. Extending upwardly from each piece is a figurine of animal-like character. Selective interconnection of the pieces forms an infinite variety of groupings of the pieces for play and display.

A process is disclosed for creating three-dimensional figures or forms starting from any flat surface image. The process includes the steps of selecting an illustration to be reproduced in three dimensions and then preparing an assistance plan for the assembly starting from the figures own, or cast, shadow. Thereafter, contour drawings are made of each piece, joining each point that defines a level, following the model's contour until arriving back at the point of departure. The design is then broken down by drawing each of the component pieces thereof individually and cataloging them and grouping them by material, texture and color; making the pieces obtained from the individual drawings, then grouping and cataloging by level each of the fabricated pieces. A base or theoretical point is space is determined over which the work will be assembled; marking at level zero, or the base, the position at which level one will be placed on the base. The assembly of the three-dimensional work is then commenced with the aid of the design so created, by joining corresponding pieces of level one to zero, those of level two to level one, etc., until arriving at the last level planned.

A toilet training system in which a decal having a background scene imprinted thereon is adhesively fixed to a toilet lid and a plurality of appliques, each of which depict an entity belonging to the aforementioned background scene, are provided as individual rewards for a successful potty experience. The child attaches the appliques to the decal to build up a scene.

In accordance with an embodiment of the present invention, there is provided a plurality of color-coded cards and representing four personality styles and a set of two cards representing the Extraversion-Introversion scale of Carl Jung. On each set of two (2) cards, there is one that lists twenty (20) characteristics of the particular style associated with that card on a plurality of removable strips. The other card in the set of two (2) has a blank side to place the removable strips that characterize each participant. On the reverse side of this card is printed the workplace environment that most appeals to a person of this particular style. Each card has a place for a simple score, (i.e. a simple sum of the characteristics chosen). The color-coded cards are ordered numerically. The Extravert-Introvert (E-I) card is also scored. Participants are asked to place color-coded dots representing each participant's particular order of styles on their nametags. The first style represents a participant's dominant personality style. The combination of all four styles with the Extraversion-Introversion components represents the participant's personality temperament or profile.
